Question

CHFM 101. General Chemistry Practice Problems Test 4 e re is required to reduce the volume to 1.2 1. A gas has a volume of 1.57 Lt 2.95 mm Wh at the same temperature? 2. A gas has a volume of 3.75 liters at 12°C, what is the volume at 25°C if the pressure remains constant? 3. What is the pressure of a gas in a 375 mL container, if it has a pressure of 219 Torr in a 525 ml container at the same temperature? 4. What is the pressure of a gas in a 2.00L container at 35°C if it has a pressure of 117 mm Hg in a 1.75L container at 45°C?

Answer 1

Initially Finally Volume (Vi) - 1.574 volume (V2) = 1.25L Pressure ( R ) = 2.9 sation pressure ( px) = ? from the Boyl's law vat (at constant I) - Pivo = P VE = $ = Prvi substitute all the values § = 2.95 atm) (1-571) = 3.9044m 1-252 si pressure crenuired) = 3.7atm

Initially Finally Volume (4) - 3751 Temperature (TV) = 12°C volume (V) = 2 Temperature (Iz) = 25°C T2 = (25+278)* १२ - २१8 = 12+273 T = 285k According to Charle's flaw, vaq (at constant Pressure). Va I T V : V. Tz substitute all the valuy (3.752) (2986) 2856 - 3.922 - Volume = 3.924 =V2
